JAMES T. DRUMMOND, OF ALTON, ILLINOIS, ASSIGNOB TO JOHN H.

MOGOWAN, OF CINCINNATI, OHIO.

TOBACCO-COMPRESS.

SPECIFICATION forming part of Letters Patent No. 238,493, dated March 8, 1881.

Application filed April 30, 1880. (No model.)

To all whom it may concern Be it known that I, JAMES T. DRUMMOND, of Alton, in the county of Madison,iu the State of Illinois, have invented a certain new and useful Improvement in Tobacco-Gompresses; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure 1 represents a front elevation of my invention. Fig. 2 represents a section of the same on the line 00 a; in Fig. 1, seen from above; and Fig. 3 represents a section of my invention on the line y y in Fig. 1.

The same letters denote the same parts in all the figures.

My invention relates to machinery for 'giving the final compression to plug-tobacco; and it consists in devices for pressing the mass of tobacco from both top and bottom, the object being to distribute the effect of the pressure throughout the mass more uniformly than it can be done with the appliances now in use,

and to avoid the defacing of the sides of the upper layers, which results from their being forced down (as by the machinery now in use they are) from four to six inches in the compress-box, their sides being scraped in the passage by the iron walls of the box.

In the drawings, A is the compress box or receptacle for the tobacco to be pressed. It is open at the top and bottom, and the upper and lower compress-blocks, B and 0, respectively entering it at the corresponding ends, fit into it. A door, a, on the front of the compress-box is opened for the purpose of putting in the tobacco to be pressed, and is fast shut when the box is full. The tobacco is put in in layers in the usual way. The compress-box is confined laterally by the standards D and the brackets (I, which are affixed to the standards at such a height that when the compressblock at each end barely enters the cavity of the box the tops of the brackets will be midway between the top and bottom of the box. In this position the box is supported by the suspension-rests a, which project from its sides and rest upon the tops of the brackets. The upper compress-block, B, is rigidly fixed to the cross-beam D, which braces the standards together at their upper ends. Thelower compress-b1ock,0,is connected or continuous with the plunger G of a hydraulic press.

The water being forced through the inlet H into the cylinder F and beneath the plunger, raises the lower compress-block, which presses upward against the lower surface of the tobacco in the box. This pressure continues until the platen or plunger-head E of the press comes in contact with the bottom of the box, when the upward pressurelit'ts the box off from the brackets 01, and the upper layers of the tobacco are pressed downward by the immovable upper compress-block, B, the bottom layers retaining their position in the box. In this way the tobacco is subjected to compression from both bottom and top successively. Substantially the same result may he attained by having the compress-box stationary and both blocks movable, and applying the compressive force to both.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The movable compress-box A, in combination with the movable compress-block O, projecting platen E, and stationary compressblock B, all so arranged that after the movable compress-block has passed into the box a certain distance the box will be moved to the stationary block and compress the contents upon two sides, substantially as described.

2. The tobacco-press substantially as described, embodying, in combination, the cylinder F, plunger G, plunger-head or platen E, side supports, D, head-piece or press-bar D, inold A, provided with guide-lugs a, and means for retaining the mold at-an elevation independently of the plunger, substantially as and for the purpose specified.
